AXLE

sPEcIFIcATIoN forming part of Letters Patent No. 413,943, dated October29, 1889.

Application filed June 4, 1889. Serial No. 313,059. (N model.)

To aZZ whom it Weary concern:

Be 1t known that I, PATRICK K. HUGHES,

a citizen of the United States, residing at;

any accidental separation, and also to pre-' vent so far as possibledust and grit from entering between the sleeve and spindlein otherwords, to provide a close-fitting device to be applied to the end of thespindle and yet maintain a freedom of action of the sleeve upon theaxle-spindle.

With these general objects in view the instruction hereinafterspecified, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a per-.

spective of a portion of an axle the spindle of which is providedwith asleeve maintained in position thereon by devices constructed inaccordance with my invention. Fig. 2 is a central longitudinal sectionof the same. Figs. 3 and 4 are details of the binding and looking nut-s,respectively. Fig. 5 is a detail view representing the end of theaxle-spindle.

Like numerals. of reference indicate like parts in all the figures ofthe drawings.

1 represents the axle, at the ends of which are formed the usualspindles or bearings 2, and at the juncture of the axle and spindle areprovided in this instance the annularlygrooved cylindrical boss 3 andthe shoulder 4. The outer end of the spindle is reduced andscrew-threaded, as at 5, the threads being disposed from right to left.Toward the extremity of the spindle a further reduction is made, as at6, and said reduced portion is screw-threaded, the threads beingdisposed from left to right.

7 represents the sleeve or axle-box, which is designed to be fittedwithin the hub of the wheel, and the same in this instance consists ofan enlarged rear end 8, having an enlarged bore 9 agreeing in size withand adapted to loosely fit the annularly-grooved boss 3 and of a depthto extend slightlyfin front of the shoulder 4, thus forming an annularrecess 10, in which is located a leather washer 11, embraced upon theone side by the shoulder 4 and upon the opposite side by the end wall ofthe recess 10. Forward of the recessedportion 10 the sleeve is reduced,as is also its bore 12, the same loosely fitting the spindle 2, saidsleeve terminating at a point slightly beyond the beginning of thereduced portion 5 and provided with an annution 17 of the binding-nutabuts. lhe nut in rear of the cylindrical portion 17 is angularly formedto adapt the same for a wrench, and is interiorly recessed, as at 19,for a purpose hereinafter specified, said recess terminating at theshoulder 20, formed at the beginning or front end of the reduced portion17. By the proper proportioning of the recess 13 and the exterior of thereduced portion 17 a ground joint 17* is formed, which, in addition tothe leather washer 14, mounted in the recess, makes the possibility ofdust or grit entering between the sleeve and spindle extremely remote.

21 represents the outer cap or what I herein term the locking-nut,andthe same consists of a hollow cap portion 22, of a length sufficientto extend beyond the juncture of the nut and the sleeve and of a sizeinteriorly sufficient to wholly receive the bindingnut 15. Thecap isprovided at its exterior forward end with a wrench-receiving surface 23and an exterior annular boss 24 intermediate its ends, adapted to bereceived by and approximately fit the outer hub-band of a wheel. The capwithin its bore 25 is provided with a rearwardly internally-bored andscrew-threaded collar 26, the bore and thread of which are adapted tocoact with the reduced spindle portion 6, and by this means said capacts as a lock-nut for the binding-nut 15, the threads of the two, likethose on the portions 5 and 6, being oppositely disposed.

The exterior surface of the collar 26 is of a size adapted to snugly fitthe inner wall of the annular recess 19, formed in the nut 15, thusforming a second ground joint 27.

By the construction described it will be apparent that while the sleeveor axle-box will be perfectly at liberty to revolve upon the spindle itwill without binding against metal be snugly held upon its properbearing, and, furthermore, that by the arrangement described dust, grit,and water will be prevented from entering between any of. the partscomposing the device.

Having described my intention, what I claim is 1. The combination, withthe spindle 2, terminating in the reduced portions 5 and 6, oppositelyscrew-threaded, of the sleeve or axlebox '7, projecting slightly beyondthe beginning of the reduced portion and terminating in the annulargroove 13, having the washer 14, the binding-nut 15, threaded on theportion 5 and having a reduced rear portion forming a ground joint withthe recess 13, and having a forward annular recess-19, and of thelock-nut 21, having the internal bore provided with theinteriorly-threaded integral collar 26, mounted on the reduced portion6, the exterior of said collar taking within the annular recess 19 ofthe nut 15 and forming a ground joint with the wall of the same, saidlock-nut having the hollow cap portion 22, which is of a lengthsufficient to wholly re ceive the nut 15 and fit around the end of theaxle-box, substantially as specified.

2. The spindle having the oppositely-th readed portions 5 and 6 at theouter end, combined with the nut 15, screwing over the threaded portion5, and the cap or set-nut 21,screwing upon the threaded portion 6 andinclosing the nut 15 and the end of the axle-box, as set forth.

3. The spindle having theoppositely-threaded portions 5 and 6 at theouter end and the axle-box on the spindle, combined with the nut 15,screwing over the portion 5 and forming a ground joint with the interiorsurface of the outer end of the axle-box, and the cap or set-nut 21,having the threaded collar 26, screwing upon the portion 6 of thespindle and inclosing both the nut 15 and the end of the axle-box, asset forth.

4. The spindle having the threaded portion 6, combined with the cap-nut21, having an interior screw-threaded collar 26 to engage with thethreaded portion 6 of the spindle, said cap-nut being extended forwardand inclosing the end of the axle-box, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

PATRICK K. HUGHES.
